The Panmixer floor liner is a replaceable lining part for the inside of the pan. It is a high wear item since it is in direct contact with the aggregate mixture and scraping of the paddle shoes causes heavy friction along the surface by abrasive material. In order to accommodate as much lifespace as possible, the metal selected is low in tensile strength (for metal) and high in abrasive resistence; However, expect to replace this part every 3 months in high production scenarios.
